Description
The Derya DY12 10-round magazine is purpose-built for extended capacity shooting on magazine-fed 12-gauge shotguns. This factory magazine gives you the ability to load up more rounds between reloads, which makes a real difference whether you're running drills at the range or practicing with tactical setups.
Built for Reliability and Durability
This magazine is constructed from steel with a corrosion-resistant blued finish that holds up against the wear and tear of range use. Inside, a polymer follower keeps rounds properly aligned while a steel spring delivers consistent feeding. Unlike standard tube-fed shotguns, magazine-fed shotguns benefit from quality components that work together smoothly, and this one delivers on both fronts.
Compatible Across Multiple Platforms
While engineered for the DY12 series, this magazine also works with several other popular AR-12 shotguns including the MKA1919, VR80, X12/F12, Boss, and AR-12. This versatility means you can use the same magazine across multiple guns if you own more than one platform, which simplifies your gear and ammunition management at the range.
Designed for Practical Use
With 10 rounds on tap, you get extended engagement capability without the bulk of a drum magazine. The magazine accepts both 2-3/4" and 3" shells, giving you flexibility with whatever ammunition you're running. For best results with magazine-fed shotguns, stick with quality ammunition engineered for mag-fed guns rather than cheap, low-velocity rounds.

Frequently Asked Questions
Is the Derya DY12 magazine compatible with other shotgun platforms?
Yes. While designed for the DY12 series, this 10-round magazine also works with the MKA1919, VR80, X12/F12, Boss, and AR-12 shotguns. This cross-compatibility is useful if you own multiple magazine-fed 12-gauge platforms and want to standardize your magazine inventory.
What type of ammunition should I use with this magazine?
For best feeding reliability with any magazine-fed shotgun, use quality ammunition engineered for mag-fed guns with smooth hulls and higher velocity loads of at least 1,250 fps. Cheap, low-velocity rounds often don't cycle well in magazine-fed shotguns. Premium loads like Federal Action Shotgun are designed specifically for this application.
Will this magazine work with both 2-3/4" and 3" shells?
Yes. This magazine accepts both 2-3/4" and 3" magnum shells. When switching between different shell lengths, you may want to adjust your DY12's piston accordingly for optimal cycling with each load type.
How durable is the Derya DY12 magazine for field use?
The steel construction with corrosion-resistant blued finish is built to handle rough range conditions and regular use. The polymer follower and steel spring inside work together to ensure smooth, reliable feeding over time, even with extended use.
